Jumbo frames are a thing.
Ill defined, but yes, definitely a thing.

> We moved, and it's not feasible to run ethernet everywhere in our current home. However, whoever built the home ran coax to nearly every room in the house - it's a bit ridiculous How old is the house? If its more than 20ish years old running coax everywhere was a great choice. That would be before CAT5e cable so if they had went with ethernet cable instead of coax you'd be looking at 100 Mb/s. If it was built befor…
Can't tell if serious or not so bravo. On the assumption you are, just climb in the loft and drag the cable over, it's not that bad, I've been in and out of lofts since my early teens doing house re-wires with my father and never put my foot through a ceiling.
This is a comment for folks in homes with coax run for cable TV. Ethernet is great. I wired ethernet to most rooms in our remodel and set up wired access points or jacks in the office to connect directly to my computer. The speeds and consistency over wifi and mesh were remarkable. Especially consistency. We moved, and it's not feasible to run ethernet everywhere in our current home. However, whoever built the home r…
I remember wiring up cat5 gigabit about 20 years ago in an industrial workplace. My house of that age also has cat5 everywhere and it’s aged very well. 1gig is still the standard for wired with few but expensive 2.5g and very expensive 10g home and small business options.
> 1gig is still the standard for wired A lot of people already get more than that from their ISP. I had at least 2.5g on every consumer product from the past 5 years. Small businesses use at least SFP on the floor level. Yada yada yada. Point is it's probably a regional thing.

Jumbo frames are not a thing on the internet. The internet has fossilized at 1500 byte MTU.
the internet has a whole bunch of non ethernet stuff, a lot of which has different frame sizes. Its totally possible that backhaul is running jumbo frames, or something like it, but you'd never really know that.
Conversely ADSL has odd frame sizes(inherited from ATM; 48 bytes if I remember correctly), but you don't see that because its hidden from you. Cable has a frame sizes ranging from ~500 up to 2000 bytes. Again, hidden from you.
One of the joys of TCP/IP is that different frame sizes are handled for you. Sure it might be beneficial to have a frame size that marries up with packet size, it might not. you don't really know, because the internets.

Ethernet is switched and under 20Mb/s is more than usable for everything unless you transfer movie files and wait, in which it would take like up a few minutes to watch a video. If you browse it's more than enough.
In that's your usecase, it's better to save yourself the hassle and just set up good WiFi

I live in a house nearing 20 years old, and was incredibly pleased when I moved in and realized that all the phone jacks in this house were backed by CAT5, and if I was willing to invest the time (which I am), I could have at least one Ethernet jack in each room, and a pair channeled up to the attic as well. My only regret was they stripped way more than needed and didn't leave a lot of wire available, but enough tha…
Implicit QoS - each device has a max 1GBps share of the 2.5GBps connection. Most hardware can't handle more anyways.
Hahaha. Love it.

Also, check the phone lines. If it's recent enough build, it will use Cat5 (or higher, but probably not) for the phone lines.

L3 switches are absolutely a thing, they allow communication between different VLANs on the same hardware without needing to go through a router.
A layer 3 switch is just a switch and a router in the same chassis. I have layer 3 switches doing eBGP.

The few times I have run into these, the actual performance is terrible. Wifi is almost always better.
Mine is, in theory, 2Gb/s. In practise, nearer 50Mb/s. It also causes interference on my amplifier, although it's a cheap amplifier. About once a year one of the adaptors loses its connection to the other adaptor, and instead connects to someone else's setup in this apartment building.
